My 2005 Road King has a speedo that does not work all the time , have had this happen twice before , dealer replaced speedo and sensor , finlly the main harness both times .then it worked fine until the next time ,which is now
Found problem ,wire from speed sensor must have break in it , my dealer ghosted a wire in it's place and has worked for a week .
they are going to pull new wire through harrness this week
